Answer: The pH of the solution will decrease by 1 unit.
Explanation:
Let say the hydronium ion concentration of a solution is 0.001
pH = - log [H+]
= -log 1.0 x 10^3 = 3
if the hydronium ion concentration is increased by 10 , that is: 0.001 x 10 = 0.01
pH = -log [1.0 x 10^2]
= 2
Therefore, the pH is reduced by 1 unit when the hydronium ion concentration is increased by a factor of 10.
Answer:
Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds.

Answer:
A. [isocitrate]/[citrate] = 0.724
B. [citrate] = 24.1 mM
Explanation:
Using the equation, ∆G'° = -RTlnK'eq
Where, ∆G'° = 0.8 KJ/mol = 800 J/mol; R is molar gas constant = 8.315 J/mol; T is standard temperature = 298 K; Keq is equilibrium constant = [isocitrate]/[citrate]
Making Keq subject of formula in the above equation;
Keq = e^(-∆G'°/RT)
= e^ {-800/(8.315*298)}
= e^(-0.323)
Keq = 0.724
Therefore, [isocitrate]/[citrate] = 0.
724
B. Keq = [isocitrate]/[citrate]
Where Keq = 0.724, [isocitrate] = 0.03mM.
[citrate] = Keq/[isocitrate]
= 0.724/0.03
[citrate] = 24.1 mM
